l COAL-qm BURNER.

' L Specification of vLetters Patent.

To all whom t may concern:

Be it known that I, PHILIr H. SrAULniNe, a citizen of the United States of America, residing at Hinsdale, in the county of Dupage and State of Illinois, have invented certain new and useful Improvements in CoalfOil Burners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a coal oil burner and has for its principal obj ect the production of afstructure which will easily Vaporize Lheoil for causing the gas to readily burn as r' discharged from the burners, the flame at vaporizing the Oil.

each burner striking against a'spreader so as to further heat the conducting pipes for Another objectA of this invention is the production off a coal oil burner wherein a minimum nurnber of parts are employed,

thus making the burner cheaper and more durable in construction, although arranging the pipes in such manner as to readily vaporize the oil beforethe same is conducted to the nipples of the burner.

Another object of this invention is the production of acoal oil burner wherein generating pans are positioned upon the pipes beneath the nipples of the burner for heating the vaporizing pipes, these pans being provided with simple and eiicient straps for supporting the same and holding the pans against side displacement.

With these 'and other objects in view, this invention consists in general of certain novel combinations, 'constructions` and arrangements of parts as will be hereinafter fully described and claimed. y

une 7 7, Fig. e, looking in the direction of are connected by the ,T 2 to a suitable supply 3 leading from a tank or lsimilar source of supply which it is not deemed necessary to disclose. The parallel side pipes 4 have vertical extensions 5 at one end, and these extensions 5 terminate in the horizontal projections 6 which are connected to the valves l. I

In order to hold the side pipes 4 from spreading, elbows 7 are carried upon their free ends and these elbows 7 are connected by a short pipe 8, as shown clearly in Fig. l.

In this manner it will be seen that the side pipes 4 will be relation.

Each side pipe comprises a primary section 9 and an auxiliary section 10. These sections are connected together by T-joints 1l and 12. The auxiliary section l0 con nected to the T-joint 11 is internally threaded, as indicated at 13 in Fig. 5, so as to receive anexternally-threaded plug 14.' By this construction it' is obvious that oil ad mitted by one of the valves into the side pipe 4 carrying the T-joint l1 will be prevented positivelyretained in spaced from passing into the auxiliary section 10` ol` the side pipe. The primary section 9 of the lrernaining side pipe is also connected to the 'T-joint 12 so as to supply this T-joint with oil when oil is admitted by the remaining valve, but in order to prevent the oil from passin into the lauxiliary section 10 or .throng the elbows'? a plug 14 is threaded into the auxiliary section 10 connected to the T-'joint 12 as shown clearly in Fig. 11. By the foregoing description, it will be seen that oil will be prevented from passing beyond the lV-joints of the respective side pipes 4.

A one-piece burner pipe is connected to each of the T-joints/ll and 12 and the con struction of the burner pipe is clearly shown in Figs. 3 and 7. The burner pipe comprises a pair of sides 15 connected by the horizontal top 16. One of the sides l5 is threaded into engagement with its respective T-joint while the remaining side is provided with a short horizont-al portion 17 terminating in a vertical burner portion 18. This burner portion is externally threaded so as to permit the burner cap 19 to be screwed thereon as is shown at 20. The burner cap 19 is provided with a reduced opening `21 for purposes to be hereinafter set forth.

The spreader 22 is` provided with a plurality of spurs 23 upon its periphery as shown clearly in Fig. 1. This spreader 22 is retained upon the horizontal portion 16 of each burner pipe by means of a clamp 2-l which fits over the horizontal portion 1G of the burner pipe for permitting the bolts 25 to be passed through the feel; 26 of the clamp 24 and through the spreader 22 for holding the spreader against accidental displacey ment. U-shaped supporting bands 27 have their ends coiled to form supporting sleeves 28 and 29. These sleeves 28 and 29 lit upon the side pipes 4 whereby .the bands will be held in engagement with these side pipes, as shown in Figs. 7 and 8. It will be noted that the sleeves 28 t upon each end ot the T-joints 11 and -12 while the bands coiiiverge toward their opposite ends. The generating pans 30 rest upon the bands 27 and fit between the side pipes l. It will further be seen by referringparticularly to Fig. 8 that these generating pans 30 are positioned below the burner carp 19. These pans are held tixedly upon the hands 2Taby means of rivets 3l whereby tlie rivetsV will hold the bands and generatingpans as' a single unit. As a consequence, since the sleeves 28 lit upon the ends. of the T-joints 11 and 12, it is obvious that the bands, and pan will be held against longitudinal movement along the side pipes since the joints will`hold the sleeves 28 from sliding in either direction. In this manner, the generating pans will be held at all times in their correct positions beneath the burner caps 19.

When this coal oil burner is in use, it is intendedto provide generating pans 30 with any suitable material such for instance, as asbestos meal or mineral wool. When it is desired to ignite either of the burners a quantity of alcohol of a suitable amount is poured into either of the generating pans and is then ignited. After the alcohol hasv been burned a few minutes, or long enough to heat the burner pipe, the proper valve is actuated for admitting oil into the burner pip Owing to the super-heated condition of the burner pipe, the oil passing therethrough will be vaporized so as to pass in the form of gas from the cap of the burner pipe, thus permitting the gas to be ignited. Therefore, a comparatively large blue flame will issue from-the burner cap which will strike against the spreader 22 carried thereabove. The iame will then pass around between the spurs 23 formed on the periphery of the spreapler so as to produce a large Haine of very intense heat. This will continue to heat the burner pipe for continuing the vaporizing of the oil as the oil passes through the burner pipe.

From the foregoing description it will be seen that a very simple and eiiicient coal oil burner has been produced which is formed of a comparatively few number of parts and which is constructed so as to prevent needless quantities of oil passing through the sections of pipe not in use while the formation of each burner will cause the oil to be quicklyV vaporized as the oil passes therethrough. It will also be seen that the generating pans are carried upon the supporting straps mounted upon the side pipes so as to hold the generating pans against longitudinal movement along the side pipes owing to the permanent connectionof these bands and the generating pan and the manner of having the sleeves of these bands engaging one of the joints of each burner pipe.

What is claimed is 1. In a coal oil burner of the class de-` scribed, the combination with a pair of side pipes, a joint connected to one of said pipes,

a burner pipe carried by said joint, U-shaped supporting bands positioned beneath said burner pipe, said bands having rolled ends thereby forming sleeves fitting upon said first-mentioned pipes, a generating pan carried by said bands, said pan being perma- -nently secured to said bands, a plurality of said sleeves engaging the ends of said joint, whereby said bands will be held against movement along said -first-mentioned pipes thereby holding said generating pan against accidental displacement.
